for that matter, day trading and technical analysis is literally just insider trading. This chart, based on some analysis of the way it's moved, with no interest in the metrics of the company itself, dictates buy or sell. Every 'Technical Trader' learns these 'indicators' and trades on them. It's just shadow insider trading under the guise of providing 'liquidity' but in reality just contributes to more volatility.
Back when the stock market was founded, it was meant as a means of providing a signal of support for a company. It allowed the company to raise debt or financing based on it's stock price or signal of support. You bought company stock because you believed in the fundamentals of the business and you wanted to support it. Now it's just about how i can sell this stock to the bigger sucker, for more money than i bought it for.
